USB issues with Ratel Performance

Hi,

On my new Ratel Performance, I have 2 USB issues:

My USB keyboard is recognized by the BIOS and by Grub, but immediately after Grub loads the default menu option, the USB keyboard stops being recognized. When the LightDM menu appears, I must wait about 10 or 20 seconds for the keyboard to be usable again.

Re: USB issues with Ratel Performance

Sorry, I have perhaps not been sufficiently explicit. By "startup", I mean when the desktop environment is fully loaded.

I've done a few tests. The external drive is already connected in a USB port when I boot on the live CD:

- With a live Ubuntu 12.04: the external drive is sometimes recognized when Unity is fully loaded (I see its icon on the Unity dash), but sometimes not. However, if I disconnect it and reconnect it in the USB port, it's always recognized.

- With a live Ubuntu 12.10: the external drive is never recognized, neither when Unity is fully loaded, nor if I disconnect it and reconnect it in the USB port. Therefore, the external drive is unusable.

About the USB keyboard:

- With a live Ubuntu 12.04: the keyboard is always recognized when I see the live menu. I choose "Try Ubuntu without installing", then sometimes the keyboard is still recognized (so I can toggle with arrows between the graphical boot process or the textual boot process), sometimes it stops working for about 20 seconds, until the desktop environment begins to load.
